LWJGL3 for OpenBSD 3.3.1.1

This release incorporates a small fix from @bsdkurt for arm64 on OpenBSD

First OpenBSD release of 3.3.1

Here is a release based upon LWJGL 3.3.1 that builds and works on OpenBSD

Many thanks to netzbasis who finished the work when I was stuck.

Second Release for BSDs

This release:

• Adds FreeBSD support (from Cameron Katri)
• Restores functionality that the Sodium mod for Minecraft uses (from Peter Hessler)
• Adds a tweak to get LWJGL3 building on OpenBSD/i386 (from Kurt Miller)

Initial version for OpenBSD

An initial working version for OpenBSD. This is based upon the in-progress 3.2.4 version of LWJGL3.

This has been tested to run versions of Minecraft >= 1.13. (Including extensive testing with 1.16.5).
